摘要： A consolidated complex shaped article having a density of at least about 95 percent of theoretical density is prepared by placing a plurality of separate bodies in an arrangement, such that each separate body is in contact with at least one other separate body to form an aggregate body and wherein at least one of the separate bodies is essentially dense. The material of each separate body is comprised of a ceramic, a cermet or a metal. The aggregate body is then consolidated at a consolidating temperature, superatmospheric pressure and time at temperature and time at superatmospheric pressure sufficient to form a consolidated shaped article. In consolidating the aggregate body, the consolidating temperature is a temperature that fails to form a liquid within at least one separate body and the superatmospheric temperature is applied for at least a portion of the time at the consolidating temperature.

摘要翻译： 通过将多个分开的主体放置在一个布置中，使得每个独立的主体与至少一个其它分开的主体接触以形成聚集体，从而制备具有至少约95％的理论密度的固结的复合成形制品 并且其中所述分离的主体中的至少一个基本上是致密的。 每个单独的主体的材料由陶瓷，金属陶瓷或金属组成。 然后将骨料在固化温度，超大气压力和在高于大气压的温度和时间下固化，足以形成固结的成型制品。 在固结聚集体时，固结温度是不能在至少一个独立体内形成液体的温度，并且在固结温度下至少部分时间施加超大气温度。
